Sheet-Pan Sausages and Mushrooms With Arugula and Croutons★

If stuffed mushrooms grew up into a main course, it would be this one-pan dinner. To start, sausages and mushrooms roast on a sheet pan, leaving behind seasoned pan drippings. Next, in a move inspired by Judy Rodgers’s roast chicken with bread salad from Zuni Café in San Francisco, torn bread pieces are tossed with the drippings, then sent back to the oven to toast. The toasted bread is then tossed with arugula, red-wine vinaigrette and the roasted mushrooms, making a great mix of crispy, tangy and spicy bites. Crusty bread can be hard to tear from the loaf, but the rough edges make a more interesting final product: To ease the process, slice the bread ½-inch-thick, then slice crosswise ½-inch thick, then tear little pieces from there.
